Feedstock and Raw Material Dynamics for Propylene Glycol Manufacturing

The primary feedstock for industrial Propylene Glycol manufacturing is Propylene Oxide (PO), regardless of the specific hydration process (direct hydrolysis, peroxidation, or older chlorohydrin routes). Hydrogen peroxide, propylene monomer, hypochlorous acid, and sodium hydroxide are also some indirect raw materials involved in the production of propylene oxide. Understanding the value chain and dynamics affecting these raw materials is vital for production cost analysis and economic viability for any manufacturing plant.

• Propylene Oxide (PO, C3H6O): Propylene oxide is the most common direct feedstock for producing propylene glycol. PO is primarily produced from propylene monomer (derived from crude oil or natural gas) either by the chlorohydrin process (an older, more environmentally challenging method) or by peroxidation processes (such as HPPO, Hydrogen Peroxide to Propylene Oxide, or PO/SM, Propylene Oxide/Styrene Monomer co-production). These prices are highly influenced by crude oil and natural gas prices, feedstock availability, and capacity utilisation rates of PO plants. Industrial procurement for high-purity propylene oxide is critical, as it constitutes a major component of the overall manufacturing expenses and the cash cost of production for propylene glycol.
• Hydrogen Peroxide (H2O2): Relevant for the Peroxidation route to PO. This strong oxidant is produced by the anthraquinone auto-oxidation process. Its pricing is influenced by energy costs (especially for hydrogen generation) and demand from various industries. Hydrogen peroxide prices experienced moderate fluctuations, largely attributed to energy cost surges and rising transportation tariffs.
• Propylene Monomer (C3H6): The primary petrochemical feedstock for propylene oxide. Its price is closely tied to natural gas and crude oil prices, and supply-demand dynamics within the petrochemical sector.
• Chlorine (Cl2) and Sodium Hydroxide (NaOH): It is relevant for the Chlorohydrin process to PO. Chlorine and sodium hydroxide are co-produced via the chlor-alkali process, which is energy-intensive. Their pricing is influenced by electricity costs and demand from various industries.
• Catalysts (for various processes): Depending on the specific PO production route and the PG hydration method, various catalysts (acidic, basic, or metal-based) are used. The cost and performance of these catalysts impact both CAPEX and recurring OPEX.
   

The increasing demand for bio-based propylene glycol derived from renewable sources (like glycerol from biodiesel production) is gaining momentum due to sustainability concerns and regulatory support. This represents a long-term dynamic potentially diversifying feedstock reliance away from purely petrochemicals.

Manufacturing Process

This report comprises a thorough value chain evaluation for Propylene Glycol manufacturing and consists of an in-depth production cost analysis revolving around industrial Propylene Glycol manufacturing.
 

Production via Peroxidation (HPPO Process for Propylene Oxide and Hydration)

The feedstock for this process includes hydrogen peroxide (H2O2) and propylene monomer. The method primarily involves the production of propylene oxide (PO) by using hydrogen peroxide as the oxidant, which is often called the HPPO (Hydrogen Peroxide to Propylene Oxide) process. In this step, propylene monomer reacts with hydrogen peroxide in the presence of a catalyst (e.g., titanium silicalite) to form propylene oxide. The resulting propylene oxide is then subjected to a hydration process, which involves reacting the propylene oxide with water in a reactor to form propylene glycol. Then, the crude propylene glycol is purified via distillation to obtain high-purity Propylene Glycol as the product.
 

Production via Direct Hydrolysis of Propylene Oxide

The feedstock for this process is propylene oxide (C3H6O). The process of direct hydrolysis of propylene oxide is the most common and widely adopted industrial method for producing propylene glycol. In this method, propylene oxide is directly hydrolysed with a large excess of water in a high-pressure, high-temperature reactor (e.g., 150−200 degree Celsius, 1.5−2.0 MPa) without a catalyst. The process leads to the formation of propylene oxide. After the reaction, the dilute propylene glycol solution is concentrated by evaporation and purified through a series of vacuum distillation steps to obtain various grades of propylene glycol as the final product.
 

Production via Chlorohydrin Process (for Propylene Oxide, then Hydration)

The feedstock for this process includes propylene monomer (C3H6), chlorine (Cl2), and water (to form hypochlorous acid), followed by sodium hydroxide (NaOH). The process involves the reaction of hypochlorous acid (formed from chlorine and water) and propylene monomer to produce propylene chlorohydrin (CH3CH(OH)CH2Cl and CH3CHClCH2OH). Further, this propylene chlorohydrin is reacted with a strong base like sodium hydroxide or calcium hydroxide to undergo dehydrochlorination, which forms propylene oxide. Then, the obtained propylene oxide is directly hydrolysed to yield propylene glycol as the final product.
